Subject: [RFC PATCH v2 0/3] Make ELOG log and trace consistently with GHES
Date: Fri, 10 May 2024 13:21:44 +0200 [thread overview]
Message-ID: <20240510112740.667445-1-fabio.m.de.francesco@linux.intel.com> (raw)
When Firmware First is enabled, BIOS handles errors first and then it
makes them available to the kernel via the Common Platform Error Record
(CPER) sections (UEFI 2.10 Appendix N). Linux parses the CPER sections
via two similar paths, ELOG and GHES.
Currently, ELOG and GHES show some inconsistencies in how they print to
the kernel log as well as in how they report to userspace via trace
events.
This short series wants to make these two paths act similarly for what
relates to logging and tracing.
--- Changes in v2 ---
- 0/3: rework the subject line and the letter.
- 1/3: no changes.
- 2/3: trace CPER PCIe Section only if CONFIG_ACPI_APEI_PCIEAER
is defined; the kernel test robot reported the use of two
undefined symbols because the test for the config option was
missing; rewrite the subject line and part of commit message.
- 3/3: no changes.
